Specification of Letters Patent.

Patented Feb. 20, 1906.

Application filed April 17, 1905. Serial No. 255,960.

To all whom t may concern.-

Be it known that I, JOSEPH F. JOY, a citizen of the United States ofAmerica, residing at Monongahela, in the county of Washington and Stateof Pennsylvania, have invented certain new and useful Improvements inLubricators for Cars, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relatesto certain new and useful improvements inlubricators for cars,- and the invention has for its object theprovision of novel means for automatically lubricating cars while theyare in motion.

My invention aims yto dispense with the labor heretofore employed forlubricating cars, this factor, in connection with rail constructions,amounting to considerable expense and time.

I have devised a novel apparatus adapted to automatically feedpredetermined quantities of oil to cars while they are in motion, theapparatus being actuated by the movement of cars over the section oftrack adjacent to the apparatus. In this connection novel mechanisms areemployed-such as pumps actuated by the cars, resilient frames, travelingmembers adapted to move with the car, and novel forms of valves forcontrolling the amount of lubricant to be fed to the carall of theseelements being combined to provide a positive and effectual lubricatorfor cars.

The present invention is particularly adapted for use in connection withmining-cars and will be hereinafter described as such; but it is obviousthat the lubricator is applicable to railways used for other purposes.

The preferred embodiments of my ,invention are illustrated in theaccompanying drawings, it being manifest that the structural features ofmy invention are susceptible to various changes without departing fromthe general spirit and scope of the invention.

Reference will now be had to the accompanying drawings, wherein likenumerals of reference designate corresponding parts throughout theseveral views, in which- Figure 1 is .a front elevation of my improvedlubricating` apparatus, illustrating the truck of a car in position tobe lubricated. Fig. 2 1s a side elevation of a movable nozzlesupportingmember. Fig. 3 is a top plan view of a cam-arm carried by my improvedapparatus. Fig. 4 is a top plan view of the nozzle-supporting member.Fig. 5 is a top plan view of one of the horizontal frames of my improvedapparatus. Fig, 6 is a side elevation of one of the side frames of theapparatus. Fig. 7 is a detail view of an angle-bar employed to brace andstrengthen the resilient framework of my improved apparatus. Fig. 8 is atop plan view of a horizontal guide carried by the framework ofmyimproved apparatus. Fig. 9 is a similar view of another guide adaptedto cooperate with the guide illustrated in Fig. 8. Fig. 10 is a detailview of a movable block adapted to reciprocate in the guides illustratedin Figs. 8 and 9. Fig. 11 is an enlarged side elevation view of aportion of the track equipped with my improved pump, illustrating thecar-actuating means. Fig. 12 is an enlarged end view of a portion of myimproved apparatus, partly in vertical section, Fig. 13 is a verticalsectional view of a novel form of valve employed in connection with theapparatus, and Fig. 14 is a top plan view ofthe resilient frame of theapparatus. i

To put my invention into practice, I have illustrated in Fig. 1 of thedrawings a crosstie or supporting-beam 1, which comprises one of thesupporting members of the track, and it is upon this track that myimproved apparatus is adapted to be supported and operated. The rails 22 of this track are provided with vertically-disposed apertures 3 3, inwhich are mounted headed depending bolts or rods 4 4. Upon the dependingends of these rods are mounted sleeves 5 5, carrying an annularcylinder-head 6, centrally of which is formed a stuffing-box 7. Upon therods 4 4 is secured the flanged end 8 of a pump-cylinder 9, nuts 10 10being employed to lock the sleeves 5 5 and the pump-cylinder upon saidrods. In the pump-cylinder is mounted a piston-head 11, carrying apistonrod 12, which extends upwardly through the stufIing-boX 7. Therail 2 is provided with a vertically-disposed aperture 15, f throughwhich protrudes the beveled end 16 of a rod 14, mounted in saidpiston-rod. The rod is screw-threaded, as indicated at 17, and providedwith a nut 1S, whereby the movement of said rod can be governed and therod adjusted, whereby it will have the desired IOO ' pierced lugs 29 29.

stroke. Between the piston-head 11 and the bottom of the pump-cylinder Imount a conical spring 19, adapted to normally retain the piston-head inan elevated position, whereby the beveled end 16 of the piston-rod willnormally protrude above the tread of the rail. This construction isidentical upon each of the rails 2 2, and reference will now be had toFig. 1 of the drawings, wherein the connections between thepumping-cylinders and a suitable reservoir are illustrated. Each of thepump-cylinders 9 is connected by pipes 20 and 21 to a main supply-pipe22, that in turn communicatesby a pipe 23 with'a suitable reservoir (notshown) that is located adjacent to the pump-cylinders 9. The pipe 21 isyprovided with a union 24 to facilitate the connecting of said pipes andthe checkvalve 25. The pipe 20 is vprovided with a T connection 26 and acheck-valve 27. 'Before describing the remainder of the connections usedwith the pump-cylinders 9 reference will be had to the resilient framesof my improved apparatus.

As before stated, the supporting-beams or cross-ties 1 are adapted tosupport my improved apparatus, and upon these cross-ties or beamsoutside the rails 2 2'I mount resilient frames consisting of two fhorizontal frames 28 28, (see Fig. 5 which are substantially rectangularin top plan view and carry upon their longer sides outwardly-extendingbolts 3() 30 are upwardlyeXtendin side frames 31 31. These side framesare su stantially rectangular in top plan view and are provided upontheir longer sides with bosses 32 32 and 33 33, and through the bosses33 33 the bolts 30 30 are adapted to extend.

The reference-numerals 34 34 designate angle-bars having apertures 35and 36 formed therein, and these angle-bars are employed for bracing theresilient frames of my improved apparatus and are preferably mountedupon the beams 1 by suitable bolts 'or spikes 37, passing through theapertures 36 and engaging said beams. The apertures 35 are employedwhereby bolts or rivets 38 can be used to secure the horizontal frame 28in engagement with the angle-bar 34, the horizontal frame being providedin its ends with apertures 39 to receive said bolts or rivets.

Another horizontal frame 40 is employed similar to the frame 28previously described. The horizontal frame 40 is mounted upon rods 4141, extending through the bosses 32 32 of the side frames 31 31.Angle-bars 42 42, similar to the angle-bars 34, are secured to the endsof the horizontal frame 40 to brace and strengthen the rectangularresilient framework of my improved apparatus. The reference-numeral 43designates a longitudinally-disposed bar which is secured to the upperrear edge of the frame to serve functionally as a brace andstrengthening-rib.

Secured to said lugs by Mounted upon the front top edge of the frame isa guide 44, having curved ends 45 45, which protrude beyond the ends ofthe frame. Mounted upon the top of the frame parallel with the guide 44is a guide 46, and the confronting edges of said guides are beveled, asindicated at 47, to receive a movable block 48. The edges ofthis blockare grooved, as indicated at 49 49, to receive the beveled edges 47 ofthe guides 44 and 46, and this construction prevents the'block 48 frombecoming disengaged from the guides after they have once been placed inposition. In one end of the block 48 I provide a vertically-disposedaperture 50, and upon said block is swiveled by a bolt 51 anozzle-supporting member 52. This member is substantially angular in topplan view and its one end is pierced, as indicated at 53 53, andgrooved, as indicated at 54. In the groove 54 is mounted a nozzle 55,which is secured therevfin by a clamping member 56 and screw-bolts 57.The nozzle 55 is provided upon its rear end with a valve 57', which isillustrated in vertical section in Fig. 13 of the drawings.`

The valve comprises a casing having an inletport 58 and an outlet-port59. These two ports are separated by an angular-disposed partition 60,having a valve-seat 61 formed therein. In the top of the valve ismounted a sleeve 62, in which is slidably mounted the stem 63 of a valve64, which is adapted to normally rest in the valve-seat 61. In the upperend of the sleeve 62 is mounted a screwthreaded stem 65, carrying a head66 and a hand-wheel 67. Mounted between the head 66 andthe stem 63 ofthe valve 64 is a coiled spring 68, adapted to normally retain the valve64 inits seat 61. The object of this valve will be presently described.The inletport 58 of the valve is provided with an elbow 69, and to thiselbow is connected a hose 70, adapted to eXtendfdownwardly through theresilient framework of my improved apparatus and connect with a couplingmember 71, carried by a pipe 72, which is connected to the T 73, carriedby the ipe 21. A suitable clamp 74 may be emp oyed for supporting thehose at an intermediate point adjacent to the resilient frame.

Upon one end of the guides 44 and 46 is mounted a bracket 75, in whichis secured a curved pipe 76. Mounted upon the end of the block 48 is aplate 77, having outwardlyextending lugs 78 78, which are adapted toengage upon each side of the clamping mem- IOO the opposite ends of theguides 44 and 46 is mounted a cam-arm 79, having a beveled edge 80. Theobject of this arm will be described in the general operation of myimproved lubricating apparatus.

Mounted diagonally across the resilient framework of my improvedapparatus is a coiled spring 81, the one .end of which is attached toone of the bolts 49, while the other end thereof is attached to one ofthe bolts 30. ln said spring is mounted a rod 82, which is made of asufficient length to fit snugly between the bolts 41 and bolt 30 andretain the resilient frame in an upright and vertical position when nototherwise moved during the operation of my improved apparatus.

The reference-numeral 83 designates an oblong catch basin or troughwhich is approximately the length of the resilient frame, and thiscatch-basin is mounted directly beneath the path of travel of the nozzle55. The catch-basin is supported by a pipe 84, communicating by a pipe85 with the main supply-pipe 23. The pipe 85 is provided with acheck-valve 86.

The reference-numeral 87 designates a pipe extending beneath the tracks2 2 to the resilient frame upon the opposite side of the tracks, andthis pipe supports a catch-basin 88, similar to the catch-basin 83. Thehose of the opposite resilient frame is connected to the T 26.

TheA apparatus constructed in accordance with my invention operates asfollows: In Fig. 1 of the drawings I'have illustrated the truck of a carin position to receive a suitable lubricant from my improved apparatus,and

the protruding ends of the axle 89 of the truck are provided withsuitable housings or oil-cups 90, in which it has been the practice toplace waste saturated with oil. As the car-truck moves into alinementwith my improved apparatus the housings or oil-cups engage the outerends of the nozzle-supporting members, slightly turnin said membersuntil the protruding ends o the nozzle 55 protrudes within the openingformed in the housings or oil-cups 90. Simultaneous with said movementthe wheels of the truck engage the beveled ends 16 of the pistons 12 12and depress the same. This movement of the piston-rods 12 12 causes thepiston-heads 11 11 to descend, forcing the contents of thepump-cylinders through the pipes 20 and 72 to the hose connections 70and tothe nozzles 55, from where the lubricant is carried into thehousings or oil-cups 90 90 of the trucks. Simultaneously with thedepression of the piston-rods 12 12 the nozzle-supporting member isbeing moved forwardly between the guides 44 and 46 on account of the endof the nozzle-supporting member engaging the housings or oil-cups 90.The nozzle-supporting members travel at approximately the same speed asthe car passing through the apparatus, and during this time thelubricant is being continuously discharged from the nozzles into thehousings or oil-cups ofthe truck. The forward movement of thenozzle-supporting member causes the spring 78 to become expanded, andupon the wheels of the truck striking the beveled face of the cam-arm 79the resilient frames will be moved outwardly from the car, causing theends of the supporting members 52 52 to become disengaged from thehousings or oil-cups 90, at which time they are returned to their normalposition by the spring 78, and the apparatus is now in position tolubricate the next succeeding car. When the piston-rods 12 12 have beenreleased by the wheels of the track, the springs 19 return thepiston-rods 12 12 to their normal position, and the pumpcylinders areagain refilled by the supplypipes 23, 22, 20, and 21.

Between the elbow 69 and the one end of the longitudinally-disposed bar43 I mount a spring 90, the one end of the spring being attached to theelbow, while the other end of the spring is attached to the bar 43, asindicated at 91. This spring is employed, whereby when the spring 7 8has returned the nozzle and block 48 to its normal position (illustratedin Fig. 14 of the drawings) the spring 90 will slightly rotate thenozzle-supporting member and turn the end of the nozzle 55 inwardly adegree or two to prevent it from being struck by the oil-cup or housing9 prior to its engagement with the end of the nozzle-supporting member,It will of course be understood that the spring 7 8 is of a greaterstrength or tension than the spring 90.

The valves 57 are employed to govern the pressure at which the oil is tobe fed into the housings or oil-cups 90. By adjusting the screws 65 themovement of the valves 64 64 can be controlled and regulated to suit thepressure of oil or lubricant passing through the valve-bodies. Thevalves 64 are adapted to close immediately upon the pressure beingreleased by the receding of the piston-heads 11 11. The amount of oil orlubricant to be ejected into the housing or oil-cups can be regulated byadjusting the nuts 18 upon the pistonrods 12, thus being employed tolengthen and shorten the stroke of the pistonrods, and consequentlyincreasing or decreasing the capacity of the pumping-cylinders. Duringthe operation of my improved apparatus should any oil drop during theoperation of ejecting oil into the housings or oilcups the catch-basinsserve to return the oil to the main supply-pipe. The check-valves havebeen employed to prevent return movement of the oil after the injectionstrokes of the piston-rods 12 12 have taken place.

From the foregoing description, taken in connection with the drawings,it will be observed that I have devised a novel automatic lubricatingapparatus adapted to quickly IOO and efectually lubricate the truckspassing through the apparatus, thus dispensing With the employment oflabor to perform this operation.
